Strain clamp for LV-ABC lines

LV ABC Strain clamps or low voltage tension clamps were developed as a confident solution for aerial bundled conductors, in low voltage insulated overhead lines.
These LV-ABC fittings are applicable for following LV-ABC cables:
• LV-ABC lines with insulated neutral messenger
• LV-ABC lines with bare neutral messenger
Tension clamps are designed to anchor self-supporting cables with insulated neutral messenger, also called as “French System”, which was 3 insulated aluminum conductor and 1 neutral messenger with insulation.
Mechanical strength for LV ABC strain clamp is enough to keep the aerial bundled cables in tight strength position, which does not allow the cable to slip from the cable fitting. This provided by wedges of clamp and commonly this low voltage ABC fittings are named as wedge type strain clamps.
LV strain clamps are made of Corrosion resistant aluminum, Flexible stainless steel bail, Weather and UV resistant fiberglass reinforced plastic.
The stainless steel bail allows installations of clamps on a bracket. LV ABC tension clamps and LV ABC brackets are available either separately or together as assembly.
Low voltage ABC assemblies passed the ultimate strength tension tests, operation experience with temperatures ranging from –60 °C up to +60 °C test, temperature cycling test, aging test, corrosion resistance test etc.
This low voltage clamps conform to the standards NFC 33 041, CENELEC EN 50483-2.
The wedge type strain clamps are self-adjusting. While installation pull the LV ABC clamp upstream to the pole, using special installation tools for LV-ABC lines like pulling sock, stringing block, lever hoist to tensile the aerial bundled cable. Measure needed distance from bracket to anchoring clamp and start to lose the tension of cable, let the clamp’s wedges anchor the cable inside by degrees.
